Abstract
The study was conducted at Casiaman, Bacnotan La Union from November 2006 to February, 2007 to determine physico-chemical characteristics and nutrient composition of composted waste paper and animal manure and its effect on the growth of pechay.
The experiment was laid out in Randomized Complete Block Design with five replications. Data were analyzed using ANOVA and DMRT for further test of significance.
After 38 days of composting and five days sun drying, the soil-compost mixtures came out with characteristics as follows; composted waste paper mixed in soil (T0) had a fine and crumbly texture, odorless, with gray color and OM of 2.51%; the pH level was 7.88, a moisture content of 38.57% and total NPK content was 0.124% (N), 0% (P₂O₅), 0.155% (K₂O), soil with chicken manure-waste paper compost (T1) was odorless which had black color, fine texture, an OM content of 12.4% and MC of 44.80%. The total NPK content was 0.573% (N), 1.145% (P₂O₅), 1.24 l% (K₂O) : soil with swine manure-waste paper compost (T2) was odorless, brownish black, an OM content of 7.94%, with a pH of 8.09 and MC content of 33.77% and a total NPK content was 0.309% (N), 0.337% (P₂O₅), 0.268% (K₂O) ; soil with sheep manure-waste paper compost (T3) was odorless, with fine texture, black color, 8.37 pH, an OM content of 6.67%, MC of 39.91% and total NPK of 0.418% (N), 0.337% (P₂O₅), 0.934% (K₂O) .
At 20 days after sprouting, the compost with sheep manure obtained the highest mean number of leaves at 4.20 while the least was obtained by the compost of waste paper alone (2.80). Only the compost with sheep manure can significantly increase the number of leaves of pechay. Although it also obtained longest leaves with a mean of 8.96 cm, the kind of animal manure did not bring about marked variation in the length of leaves of pechay.
The compost with waste paper alone produced the least width of leaves which is markedly lower than the treatments with manure. On the other hand, leaves of pechay could reach to 3. 24 cm wide using waste paper-manure compost as medium but waste paper compost alone produced the least width of leaves at 2.5 cm, which is markedly lower than those with manure.
Even at 25 days after sprouting, the fresh weight of pechay was not significantly affected by the type of compost used.
It is, therefore, recommended that when composting waste paper, it should be mixed with animal manure to hasten its decomposition and when utilized as organic fertilizer to obtain better soil quality. Nevertheless, further study should be conducted to find out the effectiveness of waste paper and animal manure on the growth of pechay because when using organic fertilizer, a longer duration of the study should be considered to arrive at a more conclusive result.
